Body Mass Index Calculator
BMI is a reliable indicator of total body fat, which is related to the risk of disease and death. It is calculated by weight in kilograms divided by height in meters squared. BMI does not measure body fat directly, but research has shown that BMI correlates to direct measures of body fat and can be considered an alternative measures of body fat.
It is important to remember, however, that BMI is calculated from an individual's weight which includes both muscle and fat. As a result, some individuals may have a higher BMI, but not have a higher percentage of body fat. For example, an athlete may have a high BMI because of increased muscularity rather than increased body fat.
BMI is an easy-to-perform method of screening for weight categories that may lead to health problems. Overweight and obese individuals are at increased risk for many diseases, including Type 2 diabetes, coronary heart disease, hypertension, stroke, and some cancers. By maintaining a BMI below 25, you greatly decrease your risk of developing obesity-associated diseases.
It is important to remember that BMI is only one factor related to an increased risk for disease. Check out other health indicators to assess your health risks.
